Would it be possible to open mail and take an attachment during battle? And would it also be possible to ping a level up during battle and pick the feat on the fly?

I know it's kind of bullshit but I still wanna know if it's an option. Because I could get Machidai to send Rocket Lancer exp to level him up, but I'm aware that's kinda just mega bullshit in the end.

You can't mail EXP to people, especially between your own characters.
